As it is promised on WWDC 2015, Apple released iOS 8.4 for iPhone, iPad and iPod touch bringing bug fixes and its new Apple Music platform to iOS 8 users around the world. And you can refer to our post about what’s new in the latest iOS 8.4 for more information. Although there are multiple reasons not to install the newly released iOS 8.4, you are still tempted to update to the most current version iOS 8.4 right away. You are so excited to get the iOS 8.4 arrive on your iPhone 6 at first. Before that, there is one thing you must keep in mind is to sync your iPhone 6 to iTunes in case of iPhone data loss during the updating process.
All the contacts are gone? No need to panic.
Contacts are core and key information on your iPhone 6, what a depression to find out that all your contacts are gone after you finish the updating. There is no need to panic, however. You can recover the lost contacts from the iTunes backup file provided that you have created one.
How to recover the lost contacts?
There are more one way to recover the iPhone 6 contacts lost in the process of updating to iOS 8.4, actually. The first option that would come upon you must be restoring your iPhone 6 with the entire iTunes backup file. But it may take quite a time, because you have to restore all the other information together from the backup file. Besides, restoring iPhone from iTunes backup file may result in data overlapping and permanent wiping. So I would suggest a third party software iFonebox which can recover the lost contacts selectively and transfer back to your iPhone 6 directly.
What is iFonebox?
iFonebox is specialized iOS data recovery software which can recover lost contacts, notes, messages, whartsapp messages, reminders, voice memos, call history, safari bookmarks and photos etc from iPhone, iPad and iPod Touch as well as from iTunes/iCloud backup file.
You can download a free trial version of iFonebox to have a try, but you need to pay for the full version.
Now let’s get started.
Step 1: Install and run the full version of iFonebox and then click to choose the recovery mode of “Recover from iTunes Backup”. And you will be presented with an interface asking to choose an backup file to recover your lost iPhone 6 contacts.

Step 2: Choose the contacts to recover by clicking on the icon of Contacts.

Step 3: Preview all the exported contacts and do some modifications if you want. You can also choose whichever you want to recover by checking them. Or you can choose recover the lost ones only by check “Only display deleted items” if you lost part of your contacts.
